ANIMAL-FAT I RODUGT AND PROCESS OF MAKING- THE SAME.

Specification of Letters Patent.

Patented Aug. 3, 1909.

Application filed July 3, 1908. Serial No. 441,862.

To all whom it may concern:

Be it known that I, JOHN FILBERT, a citizen of the United States, residing at Baltimore, in the State of Maryland, have inyented certain new and useful Improvements in Animal-Fat Products and Processes of of which-the following is a spec1iication.-

This invention relates to an improvement in animal fats which are from whichthe more oily part has been sep arated, such as the Well known articles of commercial stearin, an article terined.oleo stock, and also edible t-allow; theseare known dry fats. The improvemehtconsists in imparting to the said animal fats the odor, flavor "or essence of animal crackling or other form of animal tissue.

The manufacturers of animal products make so-called lard compounds or substitutes for lard, that contain a large percentage of cottonseed oil and certain ingrediwhen.

cuts for giving vary in their composition; the stiffening ingredients are always animal fats and are generally the productsof beef fats in one form or another. One manufacturer, for instance, will use oleo stearin, another will use olefo stock, and still another will use edible ta low, but in making these compounds whichare substitutes for lard all of the manufacturers use cotton-seed,oil.

' While the cotton-seed oil is wholesome as an alimentary article, it has the objection that develops a disagreeable odor when heated; and as the prepared products. of animal fats herein referred to have but little odor or flavor, they do not materially modify the unpleasant odor due to the oil, that arises when the food compounds of whichthey are part,

are heated. This odor is always developed the necessary domestic operations of cooking. This unpleasantodor is not attributable to the prepared beef fats, because they are almost neutral and are comparatively free ofodor, but is due to the cotton-seed oil which is the predominating ingredient in the said food compounds.

One of the inventive ideas that I wish to disclose is that the nearly neutral products of beef fats referred to, may be imbued with an odor or flavor more or less intense, and

that when so flavored these fats or any one of them will not only serve .to give body or nearly odorless, and

body or .for stiffening that these food compounds are heated in to stiffen the cotton-seed oil food compounds, but will also serve the new purpose of modifying the unpleasant odor of the cotton-seed oil and converting it into an odor that is unobjectionable; Y

' l have found fresh animal crackling contains a valuable essence or flavor that may be used to overcome the objectionable odor of cotton-seed oil.

In rendering animal fats, either of the hog or the beef, by the open-kettle process, heat is employed to about 280 degrees F. During the rendering operation the small particles of all tissue, which by nature are distributed through the fat, is alfected by becoming slightly brown and rising to the surface from which it is removed. This cooked animal tissue is collected and while hot is put in a. press and the oil is expressed from it; the residium left in the press is 'in the The object of the presentinvention is to imbue the prepared products of animal fats such as oleo stearin, oleo stock and. edible tallow which are nearly neutral as to odor, with the essence, odor or flavor/of fresh animal crackling, in order that when said products are used as stiffening ingredients in cotton-seed oil food compounds, their strong flavor will overcome, suppress or-at least modify the objectionable odor occasioned by the cotton-seed oil.

- The present invention therefore consists in an article of manufacture comprising the prepared products of animal fats which are almost neutral but have been imbued With the odor or flavor of animal tissue, such as hog crackling or beef crackling:

The invention also consists of a process for imbuing the prepared products of animal fats which are nearly neutral as to odor, with 'the essence, odor or flavor of animal tissue of crackling-either hog or beef.

In carrying out my invention 1 take any of the prepared beef fats, or derivatives of beef fats, such as stearin', and apply heat in order to reduce it to a liquid .condition like that of oil, and then add an equal quantity, or nearly an equal quantity of animal crackling and bring the mass to a temperature of say 350 degrees Fahrenheit. By this step the prepared beef fats or the derivatives of beef 'fats, will become imbued with the essence,

odor or flavor of the crackling, and when the form of a dense cake or mass of animaltis- 'sue, and is known as crackling.

blend has been eflected and while the mass isin a liquid condition, the crackling is to be separated from the mass by filtration or otherwise. After the separation of the crackling from the prepared beef fats, or the derivatives of beef fats the latter will congeal and assume their normal semi-solid condition, and will have the-odor or flavor of the crackling. These flavored products of beef fat or their'derivatives, are especially 1 adapted for imparting the property of body and stiffening to food compounds iu'which j'cotton-seed oil is an ingredient; such compounds will have the pleasant odor or flavor offthe crackling and the objectionable odor of thecotton-seed oil will 'not predoniinate.

It will be understood that the essential idea of this invention is to imbue any of the beef fats, or products of beef fats, with the essence, flavor or odor of animal crackling,-

aiid that the steps-herein described of reducing the beef fats to a liquid condition, adding animal crackling, and then separating the crackling from the beef fats is one of perhaps several ways in which this imbuing may be accomplished.

Having thus described my invention what of beef fat having the flavor of hog crackling."

at. 'The ing of heating a product of animal fat which normally is nearly neutral as to odor and reducing such fat to a liquid condition; adding thereto animal crackling to imbue the said liquid fat with the essence, odor or flavor of the said animal crackling; and then separating the said crackling from the said product of beef fat.

In testimony whereof I a'iiix my signature in presence of two witnesses,
